ATENT UPTON MILLER, OF MOUNT MORRIS, ILLINOIS.

SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 266,497, dated October 24, 1882,

Application filed May 5, 1882. (No model.)

To all whom it may concern:

Beit known that I, UPTON MILLER, of Mount Morris, in the county of Ogle and State of Illinois, haveinvented anew and Improved Spring Bed-Bottom, of which the following is a full, clear, and exact description.

The invention consists in the combination,

- with the springs of a bed-bottom, of links attached to these springs, and to spiral rings between these springs, and in chains connecting the springs of the pivoted head-rest with the springs of the fixed part of the bed-bottom.

The invention also consists in curved ratchet-bars hinged to the pivoted head-rest and connected at the lower ends by a hinged bar which can be raised at the middle by means of a cord to disengage the ratchet-bars to permit adjustment of the head-rests, which ratchet.- bars are separated automatically by the weight of the hinged cross-bar when the same is released.

Ret'erence is to be had to the accompanying drawings forming part of this specification, in which similar letters of reference indicate corresponding parts in allthe figures.

Figure l is a longitudinal elevation of my improved bed-bottom. Fig. 2 is a crosssectiona-l elevation of the same on the line a: m, Fig. 1. Fig. 3 is a detail plan view of part of the same.

The spiral springs A, resting on and attached to the slats B, are connected by links 0, attached to the springs A, and to spiral rings D between them, as shown in Figs. 1 and 3. The springs of the hinged head-rest E are connected with the springs on the fixed part by means of chains F. The side bars or supporting-bars G of the head-rest E are pivoted to the middle bars H of the fixed part of the bed-bottom. Curved ratchet-bars J, having the teeth on the surfaces facing theside bars H, are pivoted to the side bars G of the head-rest E, and these ratchet-bars J are connected by a crossbar, K, pivoted to the lower ends of the same, and provided with a central hinge, L, at the lower surfaces, so that the middle of this crossbar K can be swung upward. The middle or hinged part of the cross-bar K is weighted by means of blocks M, oflead, therein,for the purpose of causing this middle part of the hinged part to descend readily and automatically. A cord or chain, N, is attached to the middle of this hinged cross-bar K and passes through an eye, 0, loop, or equivalent on the outer or swinging end of the pivoted head rest E. Plates P, on which the teeth of the curved ratchet-bars J can catch, are attached to the upper surfaces of the fixed side rails H and project from the inner sides of the same.

The operation is as follows: It the head-rest E is to be raised or lowered, the cord E is pulled to raise the middle of the hinged crossbar K, whereby the lower ends of the ratchet-bars J will be drawn toward each other and the racks will be disengaged from the plates P, thus permitting the head-rest to be raised or lowered, as may be desired. As soon as the cord N is released the middle of the hinged cross-bar K is lowered by its weight and presses the lower ends of the curved ratchet-bars J outward, whereby the same will be engaged with the plates 1 and the head-rest will be locked in posit-ion.

Having thus fully described myinvention, I claim as new and desire to secure by Letters latent- 1. In aspriug bed-bottom, the combination,

with the spiral springs A, of the links O and the spiral rings D, substantially as herein shown and described, and for the purpose set forth.

2. In a spring bed-bottom, the combination, with the spiral springs A, of the links 0 the spiral rings D, and the chains F, connecting the springs of the pivoted head-rest and those of the fixed part of the bed-bottom, substantially as herein shown and described, and for the purpose set forth.

3. The combination, with a bed-bottom and its pivoted head-rest, of ratchet-bars hinged to the head-rest, and ot' a hinged bar connecting the lower ends of these ratchet-bars, substantially as herein shown and described, and for the purpose set forth.

4. The combination, with a bed-bottom and its pivoted head-rest, of the ratchet-bars J, hinged to the head-rest, the hinged bar K, attached to and connecting the lower ends of these ratchet-bars, and the cord N, attached to this hinged crossbar K for raising it at the middle, substantially as herein shown and desubstantially as herein shown and described, scribed, and for the purpose set forth. and for the purpose set forth.

5. The combination, with a bed-bottom and its pivoted head-rest, of the ratchet-bars J, 5 hinged to the head-rest, the hinged cross-bar WVitnesses:

K, and the plates P, attached to the upper VILLIAM H. MILLER, surfaces of the side bars H of the bedbottom, JOHN T. STEWART.
